We have this online homework we have to do for my chem class and my professor never went over any problems like these and I have no clue what to do... It's all about molality and density:
An aqueous solution of chromium(III) nitrate has a concentration of 0.164 molal.
The percent by mass of chromium(III) nitrate in the solution is:
An aqueous solution is 0.500% by mass ammonia, NH3, and has a density of 0.996 g/mL.
The molality of ammonia in the solution is:
An aqueous solution of chromium(III) nitrate has a concentration of 0.164 molal.
